Flight attendants at both American and United are still not flying together years after their mergers were finalized. United recently announced that flight attendants will likely fly together once a common crew management system is in place in October 2018. American previously announced that full operational integration (FOI) would occur in mid-2017 but delayed FOI until October 2018 citing IT challenges. In comparison, Delta flight attendants were able to fly together six months after final resolution of representation.
